Encapsulation and Sealing
Crawl Space Encapsulation
Encapsulation covers the soil and walls with a heavy vapor barrier, seals the vents and gaps and adds insulation and humidity control where needed. The result is a clean, dry, conditioned space that protects the wood and keeps damp air from rising into the house.

Questions
About crawl space encapsulation
Does encapsulation cure a wet crawl space?
It controls moisture from the soil and air. If water enters as liquid, we add drainage or a sump first, so the space is dry before it is sealed.
Do I still need a dehumidifier?
Often yes, especially in humid climates. We size one to the space and its condition during the plan.
